A camcorder has a power rating of 16 watts. If the output voltage from its battery is 8 volts, what current does it use?
Answers
The equation for power is,
Power
Where P is power is Watts
I is current in Amperes
V is voltage in volts
Given, power of the camcorder = 16 Watts
Output voltage from its battery = 8 Volts
Calculating the current in Amperes from power and voltage,
I =
= 2 A
Therefore the current used will be 2 A.
Power is defined as product of current multiplying voltage, that is
P=I×V
Here, P is the power,
I is the current
While V is the voltage
Here,
P is 16 watt
V is 8 volt
I is the current, that needs to be determined,
Putting the values in the equation
16=I× 8
I=2
So, When a camcorder has a power rating of 16 watts. If the output voltage from its battery is 8 volts, what current is 2 A

Hi there!
Analyzing This Question Correctly We Can conclude thatthe Most accurate and correct answer is D.
We Can conclude to this By using The collision theory.The Collision Theory states that in order for a reaction to proceed, the reactant particles must collide. The more successful collisions there are per unit of time, the faster the reaction will be.
Factors which can affect the rate of a reaction include:
⚛ concentration
⚛ temperature
⚛ particle size
⚛ catalysts
⚛ stirring rate
⚛ light intensity
For Example, By adding less Baking soda to Vinegar the less Co2(Carbon Dioxide) Will Be created.
By Adding More Baking Soda to vinegar, more Co2 Will Be created.

number of moles : 8.4 / 40.0 => 0.21 moles
1 mole ---------------- 6.02 x 10²³ molecules
0.21 moles ---------- ?
molecules : ( 0.21 ) x ( 6.02 x 10²³ ) / 1
= 1.264 x 10²³ molecules

Final answer:
There are 17 known types of elementary particles which include quarks, leptons, and force carriers. Composite particles, such as protons and neutrons, derived from these elementary particles, add to the variety of particles. The total count may change as our understanding of physics evolves.
Explanation:
When we talk about different kinds of particles in the world, we're usually referring to elementary particles, of which there are currently 17 types understood by scientists. These include six types of quarks, six types of leptons, and five types of force carriers (the photon, three types of W and Z bosons, and the gluon). Additionally, there is the Higgs boson, responsible for giving particles their mass. However, it's essential to also consider composite particles, such as protons and neutrons, made up from quarks. The exact number of particle types can be hard to quantify due to discoveries of new particles and our ever-evolving understanding of physics.

We are going to use the formula,
Number of moles = Number of molecules / Avogadro's number
We have the number of molecules: 2.0 x 10^22
Avogadro's number: 6.02 x 10^23
Now we will plug in our information in a scientific calculator:
(2.0 x 10^22) / (6.02 x 10^23) = 0.03 moles is our answer.
